Front Panel Power Switch
To prevent malfunction caused by accidental touching, the front power switch of thisequipment turns on the power if it is pressed continuously for about one second in thestandby state. If the switch is pressed continuously for one second in the power-on state, theequipment enters the standby state.
In the power-on state, if the power plug is removed from the outlet, then reinserted into it,the power will not be turned on. Also, if the lines is disconnected due to momentary powersupply interruption or power failure, the power will not be turned on (enters the standbystate) even if the line is recovered.
This is because this equipment enters the standby state and prevents incorrect data frombeing acquired when the line has to be disconnected and reconnected.
For example, if the sweep time is 1,000 seconds and data acquisition requires a long time,momentary power supply interruption (power failure) might occur during measurement andthe line could be recovered automatically to power-on. In such a case, the equipment maymistake incorrect data for correct data without recognizing the momentary power supplyinterruption.
If this equipment enters the standby state due to momentary power supply interruption orpower failure, check the state of the measuring system and press the front power switch torestore power to this equipment.
Further, if this equipment is built into a system and the system power has to bedisconnected then reconnected, the power for this equipment must also be restored bypressing the front power switch.
Consequently, if this equipment is built into remote monitoring systems that use MODEMs,the standby function of this equipment must be modified.
xi
ABOUT DETECTION MODE
This instrument is a spectrum analyer which uses a digital storage system. The spectrumanalyzer makes level measurements in frequency steps obtained by dividing the frequencyspan by the number of measurement data points (501). This method of measurement cannotdetect the signal peak level if the spectrum of a received signal is narrower than thesefrequency steps.To resolve this problem, this instrument usually operates in positive peak detection modeand normal detection mode. In the positive peak detection mode, the highest level within thefrequency range between the sample points can be held and traced. In the normal detectionmode, both the positive peak and the negative peak can be traced.Positive peak detection mode should be used for almost all measurements including normalsignal level measurement, pulsed noise analysis, and others. It is impossible to measurethe signal level accurately in sample detection mode or in negative peak detection mode.Use of sample detection mode is restricted to random noise measurement, occupiedfrequency bandwidth measurement for analog communication systems, and adjacent-channel leakage power measurement, etc.
Measurement Item• Normal signal ..................................................................................................POS PEAK• Random noise ..................................................................................................SAMPLE• Pulsed noise .....................................................................................................NORMAL (POSI-NEG)• Occupied frequency bandwidth, adjacent-channel leakage power ..........SAMPLE

Product Outline
The MS2665C/67C/68C spectrum analyzer (henceforth called "this unit") is a portable type color LCD spectrum
analyzer suited for signal analyses of radio equipment where the efficiency of frequency usage is increased and
equipment are increasingly speeded and digitized.
Excellent in basic performance such as C/N, distortion, frequency/level accuracy, and easily operable following
the display of the soft-key menu screen.
Excellent cost performance with rich options to cope with various applications.
Equipped with high-accuracy calibration signals and an attenuator, it can accurately calibrate switching errors
of LOG/LIN scales, resolution bandwidth, reference level, etc. Since frequency response is corrected by built-
in calibration data, it allows high-accuracy level measurement for a wide range.
As the switching of waveforms between frequency domain and time domain can be done by a touch and two
waveforms are simultaneously displayed, signal analyses of both domains can be done efficiently. Moreover,
our original zone marker function and multi-marker function (up to 10 markers) are also special mention.
This unit provides the MEASURE function that can perform measurement of various applications without
requiring the intervention of external controllers. Therefore, the performance evaluation of radio equipment
can be easily done in terms of frequency, noise, occupied frequency bandwidth, leak power from neighboring
channels, etc.
In addition, as the template measurement of burst mean power and burst waveform are also available, it is
suited for evaluating the performance of digital radio equipment.
Application
This unit is useful for the production, building and maintenance of electronic equipment and devices in the
following fields.
• AM/FM radio equipment
• Digital cellular telephone/cordless telephone
• Satellite broadcasting, CATV and TV equipment
• Microwave equipment

Installation Site and Environmental Conditions
Locations to be avoided
The MS2665C/67C/68C spectrum analyzer operates normally at temperatures from 0 to 50 ˚C. However, for
the best performance, the following locations should be avoided.
• Where there is severe vibration
• Where the humidity is high
• Where the equipment will be exposed to direct sunlight
• Where the equipment will be exposed to active gases
In addition to meeting the above conditions, to insure long-term trouble-free operation, the equipment should
be used at room temperature and in a location where the power supply voltage does not fluctuate greatly.
CAUTION
If the MS2665C/67C/68C spectrum analyzer is used at normal temperatures after it has been
used or stored for a long time at low temperatures, there is a risk of short-circuiting caused by
condensation. To prevent this risk, do not turn the MS2665C/67C/68C on until it has been
allowed to dry out sufficiently.
Fan clearance
To suppress any internal temperature increase, the MS2665C/67C/68C has a fan on the rear panel as shown in
the diagram below. Leave a gap of at least 10 cm between the rear panel and the wall, nearby equipment or
obstructions so that fan ventilation is not blocked.

Safety Measures
This paragraph explains the safety procedures which should be followed under all circumstances not to counter
the risk of an accidental electric shock, damage to the equipment or a major operation interruption.
Power-on
WARNING
• Before power-on: The MS2665C/67C/68C spectrum analyzer must be connected to
protective ground.
If the power is switched on without taking this countermeasure,
there is a risk of receiving a accidental electric shock. In addition, it
is essential to check the power supply voltage. If an abnormal volt-
age that exceeds the specified value is input, there is accidental risk
of damage to the MS2665C/67C/68C and fire.
• During power-on To maintain the MS2665C/67C/68C, sometimes it is necessary to
make internal checks and adjustments with the covers removed
while power is supplied. Very-high, dangerous voltages are used in
the MS2665C/67C/68C, if insufficient care is taken, there is a risk of

Preparations before Power-on
This unit operates normally when it is connected to an AC 85 to 132 V, or AC 170 to 250 V (automatic voltage
change) 47.5 to 63 Hz AC power supply. To prevent the following problems, take the necessary procedures
described on the following pages before power is supplied.
• Accidental electric shock
• Damage caused by abnormal voltage
• Ground current problems
Note: • The voltage and current rating are indicated on the rear panel when the instrument is shipped
from the factory.
• In this manual, the power supply voltage and current ratings are represented by AC ** V and
*** A, respectively.
To protect the operator, the following WARNING and CAUTION notices are attached to the rear panel of the
MS2665C/2667C.
WARNING
Disassembly, adjustment, maintenance, or other access inside this instrument by unqualified
personal should be avoided. Maintenance of this instrument should be performed only by
Anritsu trained service personnel who are familiar with the risk involved of fire and electric
shock. Potentially lethal voltages existing inside this instrument, if contacted accidentally,
may result in personal injury or death, or in the possibility of damage to precision components.
Always follow the instructions on the following pages.
SECTION 2 PREPARATIONS BEFORE USE
2-8
Connecting the Power Cord
Check that the [Line] switch on the rear panel is turned off.
Insert the power plug into an outlet, and connect the other end to the power inlet on the rear panel. To ensure
that the instrument is earthed, always use the supplied 3-pin power cord, and insert the plug into an outlet with
an earth terminal.
WARNING
If the power cord is connected without the instrument earthed, there is a risk of receiving a
fatal electric shock. In addition, the peripheral devices connected to the instrument may be
damaged.
When connecting to the power supply, DO NOT connect to an outlet without an earth terminal.
Also, avoid using electrical equipment such as an extension cord or a transformer.
CAUTION
If an emergency arises causing the instrument to fail or malfunction, disconnect the instru-
ment from the power supply by either turning off the [Line] switch on the rear panel, or by
pulling out the power cord or the power inlet.
When installing the instrument, place the instrument so that an operator may easily operate
the [Line] switch.
If the instrument is mounted in a rack, a power switch for the rack or a circuit breaker may be
used for power disconnection.
It should be noted that, the [Power] switch on the front panel of the instrument is a standby
switch, and cannot be used to cut the main power.
SECTION 2 PREPARATIONS BEFORE USE
2-9
Replacing fuse
WARNING
• If the fuses are replaced while power is supplied, there is a serious risk of electric shock.
Before replacing the fuses, set the power switch to OFF and remove the power cord from
the power outlet.
• If power is supplied without protective grounding, there is a risk of accidental electric shock.
In addition, if the AC power supply voltage is unsuitable, there is a risk of the internal circuits
of the MS2665C/2667C being damaged by the abnormal voltage. Before supplying power
again after changing the fuses, check that the protective grounding described previously is
still connected, and check that the AC power supply voltage is suitable. Then, set the power
switch to ON.
CAUTION
When there are no supplied spare fuses, the replacement fuses must have the same rated
voltage and current as the fuses in the fuse holders.
• If the replacement fuses are not of the same type, they may not fit correctly, there may be a
faulty connection, or the time taken to for the fuses to blow may be too long.
• When an abnormality occurs again, if the voltage and current rating of the fuses is incorrect,
the fuses may not blow with a consequent risk of damage to the equipment by fire.
SECTION 2 PREPARATIONS BEFORE USE
2-10
This instrument with standard accessories has two spare 5 A fuses. The fuses are mounted in the fuse holder
and must be replaced if they blow. If the fuses must be replaced, locate and remedy the cause before replacing
the blown fuses.
After performing the safety procedures described on the preceding page, replace the fuses according to the
following procedure.
Step Procedure
1 Set the front-panel [Power] switch to Stby and the rear-panel [Line] switch to OFF. Then,
remove the power cord from the power-supply outlet.
2 Place the tip of a ball point pen in the groove of the fuse holder and pull the fuse holder
towards you. Then remove the cap, together with the fuse.

Performance Test
The warm-up time depends on the test item. For test item other than oscillator frequency, warm-up the equipment
for at least for thirty minutes and test the performance after the MS2665C/67C/68C stabilizes completely.
Also, begin measurement after taking the warm-up time of the calibration instrument into full consideration.
In addition, the test must be conducted at room temperature; there must be little AC power supply voltage
fluctuation, and no noise, vibration, dust, humidity, etc.
In case of MS2667C/68C, if coaxial cable for the performance test is N type connector, connect the coaxial
adaptor 34AKNF50 (DC to 20 GHz, sold separately) to the MS2667C/68C.

Reference oscillator frequency stability
The 10 MHz reference oscillator is tested for frequency stability.
In case of MS2665C, 10 MHz reference oscillator is option 01.
Stability is determined by measuring frequency variation after 24 hours and after 48 hours of power on at
ambient temperatures of 0°C and 50°C.
In case of MS2665C, if a device is not to mount Option 01, this test is not available since there is no 10 MHz
reference buffer output.

(4) Procedure
Aging rate/day: Test this at the ambient temperature ±2˚C in a vibration-free place.
Step Procedure
1 Set the change over switch (FREQ STD: INT/EXT) on the MF1601A counter rear panel to
EXT.
2 Set the power supply switch on the spectrum analyzer rear panel to On and then the Power
switch on the spectrum analyzer front panel to On.
3 Measure the frequency using the counter with 0.1 Hz resolution after 24 hours have passed
after turning the power ON.
4 Measure the frequency using the counter after 24 more hours have passed from the step 3
measurement.
5 Calculate the stability by using the following equation.
Frequency stability =(2nd reading of the counter) – (1st reading of the counter)
(1st reading of the counter )
Temperature stability: Test this performance in a vibration-free constant-temperature chamber.
Step Procedure
1 Set up the spectrum analyzer in a constant-temperature chamber at 25˚C in the same setup.
2 Set the LINE and Power switches on the spectrum analyzer to On and wait until the spectrum
analyzer internal temperature stabilizes (approx. 1.5 hours after the chamber temperature
stabilizes).
3 When the internal temperature stabilizes, measure the frequency by using the counter with 0.1
Hz resolution.
4 Change the chamber temperature to 50˚C.
5 When the chamber temperature and the spectrum analyzer internal temperature re-stabilize,
measure the frequency by using the counter.
6 Calculate the stability by using the following equation.
Temperature stability =(counter reading at 50˚C) – (counter reading at 25˚C)
(counter reading at 25˚C)
7 Change the chamber temperature to 0˚C and repeat steps 5 and 6.
SECTION 6 PERFORMANCE TESTS

Frequency readout accuracy
Add the known frequency which serves as the center frequency reference to the spectrum analyzer as shown in
the figure below and set CF (same value as the known reference frequency) and SPAN. At this time, check that
the difference between the reading of the marker readout frequency (thick arrow in the figure) of the center
frequency peak point, and the CF set value is ≤specifications.
As shown in the figure, the Synthesized Signal Generator uses the signal source phase-locked with the same
accuracy as the frequency standard.
(1) Specifications
Frequency readout accuracy:
• MS2665C: ± (Readout frequency × frequency reference accuracy + span × span accuracy + 100 Hz × N);
Span ≥ 10 kHz × N (after calibration)
• MS2667C/68C: ± (Readout frequency × frequency reference accuracy + span × span accuracy);
Span ≥ 10 kHz × N (after calibration)
(N is harmonic order at mixer)

Resolution bandwidth (RBW) and selectivity
If there are two input signals with the frequency difference corresponding to 3 dB bandwidth (of IF final
stage), these signals can be resolved as two spectrum waveforms.
This is called the resolution bandwidth.
Selectivity can be improved by narrowing the 60 dB bandwidth. The selectivity is defined by the ratio of the
filter width, in Hz, at the –60 dB point, to the filter width, in Hz, at the –3 dB point, as shown in the formula
below.

To test the resolution bandwidth and selectivity, first measure the resolution bandwidth (3dB bandwidth), then
the 60 dB bandwidth and calculate the 60 dB/3 dB bandwidth ratio.

Sideband phase noise
When the resolution bandwidth is set to a fixed value and a signal that has far less sideband-noise level than the
equipment to be tested is input, check the level of the noise as compared to the peak signal (dBc) at the
specified frequency away from the peak.
Since the average value is measured for noise level, use a
video filter for measurement.
This sideband noise is a spectrum response which is
modulated by the internal noise of the spectrum analyzer. If
this response is large, the actual filter envelope is masked by
the noise as shown, which makes measurement impossible.

Second harmonic distortion
Even if a signal without harmonic distortion is input to a spectrum analyzer, the higher harmonics are generated
by the analyzer input-mixer non-linearity and are displayed on the screen.
The second harmonic level is the highest harmonic displayed on the MS2665C/67C/68C spectrum analyzer. The
main point of the test is to apply a signal (with a distortion that is lower than the spectrum analyzer internal
harmonic distortion [at least 20 dB below]) to the spectrum analyzer and measure the level difference between the
fundamental wave and the second harmonic. If a low-distortion signal source cannot be obtained, apply a low-
distortion signal to the spectrum analyzer after passing the signal through a low-pass filter (LPF).
